Now We have earnestly striven, by the help of His grace, to follow the example of Christ, Our Saviour, the Prince of Pastors, and the Bishop of our Souls, by diligently carrying on His office, entrusted by Him to the Apostles and chiefly to Peter, "whose dignity faileth not, even in his unworthy successor" (St. Leo the Great, Sermon 2, On the Anniversary of his Election). In pursuance of this object We have endeavored to direct all that We have attempted and persistently carried out during a long pontificate towards two chief ends: in the first place, towards the restoration, both in rulers and peoples, of the principles of the Christian life in civil and domestic society, since there is no true life for men except from Christ; and, secondly, to promote the reunion of those who have fallen away from the Catholic Church either by heresy or by schism, since it is most undoubtedly the will of Christ that all should be united in one flock under one Shepherd. But now that We are looking forward to the approach of the closing days of Our life, Our soul is deeply moved to dedicate to the Holy Ghost, who is the life-giving Love, all the work We have done during Our pontificate, that He may bring it to maturity and fruitfulness. In order the better and more fully to carry out this Our intention, We have resolved to address you at the approaching sacred season of Pentecost concerning the indwelling and miraculous power of the Holy Ghost; and the extent and efficiency of His action, both in the whole body of the Church and in the individual souls of its members, through the glorious abundance of His divine graces. We earnestly desire that, as a result, faith may be aroused in your minds concerning the mystery of the adorable Trinity, and especially that piety may increase and be inflamed towards the Holy Ghost, to whom especially all of us owe the grace of following the paths of truth and virtue; for, as St. Basil said, "Who denieth that the dispensations concerning man, which have been made by the great God and our Saviour, Jesus Christ, according to the goodness of God, have been fulfilled through the grace of the Spirit?" (Of the Holy Ghost, c. 16, v. 39.)
THE CATHOLIC DOCTRINE OF THE BLESSED TRINITY
Before we enter upon this subject, it will be both desirable and useful to say a few words about the Mystery of the Blessed Trinity. This dogma is called by the doctors of the Church "the substance of the New Testament," that is to say, the greatest of all mysteries, since it is the fountain and origin of them all. In order to know and contemplate this mystery, the angels were created in Heaven and men upon earth. In order to teach more fully this mystery, which was but foreshadowed in the Old Testament, God Himself came down from the angels unto men: "No man hath seen God at any time; the only begotten Son, who is in the bosom of the Father, He hath declared Him" (John 1.18). Whosoever then writes or speaks of the Trinity must keep before his eyes the prudent warning of the Angelic Doctor: "When we speak of the Trinity, we must do so with caution and modesty, for, as St. Augustine saith, nowhere else are more dangerous errors made, or is research more difficult, or discovery more fruitful" (Summ. Th. 1a, q. 31. De Trin. 1. 1, c. 3). The danger that arises is lest the Divine Persons be confounded one with the other in faith or worship, or lest the one Nature in them be separated: for "This is the Catholic Faith, that we should adore one God in Trinity and Trinity in Unity." Therefore Our predecessor Innocent XII absolutely refused the petition of those who desired a special festival in honor of God the Father. For, although the separate mysteries connected with the Incarnate Word are celebrated on certain fixed days, yet there is no special feast on which the Word is honored according to His Divine Nature alone. And even the Feast of Pentecost was instituted in the earliest times, not simply to honor the Holy Ghost in Himself, but to commemorate His coming, or His external mission. And all this has been wisely ordained, lest from distinguishing the Persons men should be led to distinguish the Divine Essence. Moreover, the Church, in order to preserve in her children the purity of faith, instituted the Feast of the Most Holy Trinity, which John XXII afterwards extended to the Universal Church. He also permitted altars and churches to be dedicated to the Blessed Trinity, and, with the divine approval, sanctioned the Order for the Ransom of Captives, which is specially devoted to the Blessed Trinity and bears Its name. Many facts confirm this truth. The worship paid to the saints and angels, to the Mother of God, and to Christ Himself, finally redounds to the honor of the Blessed Trinity. In prayers addressed to one Person, there is also mention of the others; in the litanies after the individual Persons have been separately invoked, a common invocation of all is added: all psalms and hymns conclude with the doxology to the Father, Son, and Holy Ghost; blessings, sacred rites, and sacraments are either accompanied or concluded by the invocation of the Blessed Trinity. This was already foreshadowed by the Apostle in those words: "For of Him, and by Him, and in Him, are all things: to Him be glory for ever" (Rom. 11.36), thereby signifying both the Trinity of Persons and the Unity of Nature: for as this is one and the same in each of the Persons, so to each is equally owing supreme glory, as to one and the same God. St. Augustine, commenting upon this testimony, writes: "The words of the Apostle, of Him, and by Him, and in Him, are not to be taken indiscriminately; of Him refers to the Father, by Him to the Son, in Him to the Holy Ghost" (De Trin. 1. vi, c. 10; 1. i, c. 6). The Church is accustomed most fittingly to attribute to the Father those works of the Divinity in which power excels, to the Son those in which wisdom excels, and those in which love excels to the Holy Ghost. Not that all perfections and external operations are not common to the Divine Persons; for "the operations of the Trinity are indivisible, even as the essence of the Trinity is indivisible" (St. Aug. De Trin., 1. 1, cc. 4-5); because as the three Divine Persons "are inseparable, so do they act inseparably" (St. Aug., ib). But by a certain comparison, and a kind of affinity between the operations and the properties of the Persons, these operations are attributed or, as it is said, "appropriated" to One Person rather than to the others. "Just as we make use of the traces of similarity or likeness which we find in creatures for the manifestation of the Divine Persons, so do we use Their essential attributes; and this manifestation of the Persons by Their essential attributes is called appropriation" (St. Th. 1a, q. 39, xxxix, a. 7). In this manner the Father, who is "the principle of the whole God-head" (St. Aug., De Trin., 1. iv, c. 20), is also the efficient cause of all things, of the Incarnation of the Word, and the sanctification of souls; "of Him are all things": of Him, referring to the Father. But the Son, the Word, the Image of God, is also the exemplar cause, whence all creatures borrow their form and beauty, their order and harmony. He is for us the Way, the Truth, and the Life; the Reconciler of man with God. "By Him are all things": by Him, referring to the Son. The Holy Ghost is the ultimate cause of all things, since, as the will and all other things finally rest in their end, so He, who is the Divine Goodness and the Mutual Love of the Father and Son, completes and perfects, by His strong yet gentle power, the secret work of man's eternal salvation. "In Him are all things": in Him, referring to the Holy Ghost.
THE HOLY GHOST AND THE INCARNATION
Having thus paid due tribute of faith and worship owing to the Blessed Trinity, which ought to be more and more inculcated upon the Christian people, we now turn to the exposition of the power of the Holy Ghost. And, first of all, we must look to Christ, the Founder of the Church and the Redeemer of our race. Among the external operations of God, the highest of all is the mystery of the Incarnation of the Word, in which the splendor of the divine perfections shines forth so brightly that nothing more sublime can even be imagined, nothing else could have been more salutary to the human race. Now this work, although belonging to the whole Trinity, is still appropriated especially to the Holy Ghost, so that the Gospels thus speak of the Blessed Virgin: "She was found with child of the Holy Ghost," and "that which is conceived in her is of the Holy Ghost" (Matt. 1.18, 20). And this is rightly attributed to Him who is the love of the Father and the Son, since this "great mystery of piety" (1 Tim. 3.16) proceeds from the infinite love of God towards man, as St. John tells us: "God so loved the world as to give His only begotten Son" (John 3.16). Moreover, human nature was thereby elevated to a personal union with the Word; and this dignity is given, not on account of any merits, but entirely and absolutely through grace, and therefore, as it were, through the special gift of the Holy Ghost. On this point St. Augustine writes: "This manner in which Christ was born of the Holy Ghost, indicates to us the grace of God, by which humanity, with no antecedent merits, at the first moment of its existence, was united with the Word of God, by so intimate a personal union, that He, who was the Son of Man, was also the Son of God, and He who was the Son of God was also the Son of Man" (Enchir., c. xl; St. Th., 3a, q. xxxii, a. 1). By the operation of the Holy Spirit, not only was the conception of Christ accomplished, but also the sanctification of His soul, which, in Holy Scripture, is called His "anointing" (Acts 10.38). Wherefore all His actions were "performed in the Holy Ghost" (St. Basil de Sp. S., c. xvi), and especially the sacrifice of Himself: "Christ, through the Holy Ghost, offered Himself without spot to God" (Heb. 9.14). Considering this, no one can be surprised that all the gifts of the Holy Ghost inundated the soul of Christ. In Him resided the absolute fullness of grace, in the greatest and most efficacious manner possible; in Him were all the treasures of wisdom and knowledge, graces gratis datae, virtues, and all other gifts foretold in the prophecies of Isaias (Is. 4.1, 11.23), and also signified in that miraculous dove which appeared at the Jordan, when Christ, by His baptism, consecrated its waters for a new sacrament. On this the words of St. Augustine may appropriately be quoted: "It would be absurd to say that Christ received the Holy Ghost when He was already thirty years of age, for He came to His baptism without sin, and therefore not without the Holy Ghost. At this time, then (that is, at His baptism), He was pleased to prefigure His Church, in which those especially who are baptized receive the Holy Ghost" (De Trin., 1. xv, c. 26). Therefore, by the conspicuous apparition of the Holy Ghost over Christ and by His invisible power in His soul, the twofold mission of the Spirit is foreshadowed, namely, His outward and visible mission in the Church, and His secret indwelling in the souls of the just.
THE HOLY GHOST AND THE CHURCH
The Church which, already conceived, came forth from the side of the second Adam in His sleep on the Cross, first showed herself before the eyes of men on the great day of Pentecost. On that day the Holy Ghost began to manifest His gifts in the mystic body of Christ, by that miraculous outpouring already foreseen by the prophet Joel (2.28-29), for the Paraclete "sat upon the apostles as though new spiritual crowns were placed upon their heads in tongues of fire" (S. Cyril Hier. Catech. 17). Then the apostles "descended from the mountain," as St. John Chrysostom writes, "not bearing in their hands tables of stone like Moses, but carrying the Spirit in their mind, and pouring forth the treasure and the fountain of doctrines and graces" (In Matt. Hom. I, 2 Cor. 3.3). Thus was fully accomplished that last promise of Christ to His apostles of sending the Holy Ghost, who was to complete and, as it were, to seal the deposit of doctrine committed to them under His inspiration. "I have yet many things to say to you, but you cannot bear them now; but when He, the Spirit of Truth, shall come, He will teach you all truth" (John 16.12- 13). For He who is the Spirit of Truth, inasmuch as He proceedeth both from the Father, who is the eternally True, and from the Son, who is the substantial Truth, receiveth from each both His essence and the fullness of all truth. This truth He communicates to His Church, guarding her by His all powerful help from ever falling into error, and aiding her to foster daily more and more the germs of divine doctrine and to make them fruitful for the welfare of the peoples. And since the welfare of the peoples, for which the Church was established, absolutely requires that this office should be continued for all time, the Holy Ghost perpetually supplies life and strength to preserve and increase the Church. "I will ask the Father, and He will give you another Paraclete, that He may abide with you for ever, the Spirit of Truth" (John 16. 16, 17).
By Him the bishops are constituted, and by their ministry are multiplied not only the children, but also the fathers that is to say, the priests to rule and feed the Church by that Blood wherewith Christ has redeemed Her. "The Holy Ghost hath placed you bishops to rule the Church of God, which He hath purchased with His own Blood" (Acts 20. 28). And both bishops and priests, by the miraculous gift of the Spirit, have the power of absolving sins, according to those words of Christ to the Apostles: "Receive ye the Holy Ghost; whose sins you shall forgive they are forgiven them, and whose sins you shall retain they are retained" (John 20.22, 23). That the Church is a divine institution is most clearly proved by the splendor and glory of those gifts with which she is adorned, and whose author and giver is the Holy Ghost. Let it suffice to state that, as Christ is the Head of the Church, so is the Holy Ghost her soul. "What the soul is in our body, that is the Holy Ghost in Christ's body, the Church" (St. Aug., Serm. 187, de Temp.). This being so, no further and fuller "manifestation and revelation of the Divine Spirit" may be imagined or expected; for that which now takes place in the Church is the most perfect possible, and will last until that day when the Church herself, having passed through her militant career, shall be taken up into the joy of the saints triumphing in heaven.
THE HOLY GHOST IN THE SOULS OF THE JUST
The manner and extent of the action of the Holy Ghost in individual souls is no less wonderful, although somewhat more difficult to understand, inasmuch as it is entirely invisible. This outpouring of the Spirit is so abundant, that Christ Himself, from whose gift it proceeds, compares it to an overflowing river, according to those words of St. John: "He that believeth in Me, as the Scripture saith, out of his midst shall flow rivers of living water"; to which testimony the Evangelist adds the explanation: "Now this He said of the Spirit which they should receive who believed in Him" (John 7.38, 39). It is indeed true that in those of the just who lived before Christ, the Holy Ghost resided by grace, as we read in the Scriptures concerning the prophets, Zachary, John the Baptist, Simeon, and Anna; so that on Pentecost the Holy Ghost did not communicate Himself in such a way "as then for the first time to begin to dwell in the saints, but by pouring Himself forth more abundantly; crowning, not beginning His gifts; not commencing a new work, but giving more abundantly" (St. Leo the Great, Hom. iii, de Pentec.). But if they also were numbered among the children of God, they were in a state like that of servants, for "as long as the heir is a child he differeth nothing from a servant, but is under tutors and governors" (Gal. 4.1, 2). Moreover, not only was their justice derived from the merits of Christ who was to come, but the communication of the Holy Ghost after Christ was much more abundant, just as the price surpasses in value the earnest and the reality excels the image. Wherefore St. John declares: "As yet the Spirit was not given, because Jesus was not yet glorified" (John 7.39). So soon, therefore, as Christ, "ascending on high," entered into possession of the glory of His Kingdom which He had won with so much labor, He munificently opened out the treasures of the Holy Ghost: "He gave gifts to men" (Eph. 4.8). For "that giving or sending forth of the Holy Ghost after Christ's glorification was to be such as had never been before; not that there had been none before, but it had not been of the same kind" (St. Aug., De Trin., 1. iv, c. 20).
